Star names including Sinner, Aryna Sabalenka and Alexander Zverev are among the top 20 men’s and women’s players asking the four majors for the whole field to receive a higher ratio of prize money-to-revenue.
The group also want more consultation about the structure of the sport, plus increased contributions from the Grand Slams into pension, healthcare and maternity pots.
While Tennis Australia’s 2025 accounts have not yet been made public, the Australian Financial Review reported, external the governing body – whose income is largely generated by the Australian Open – earned $697.2m (£346m) in total revenue.
That figure would mean this year’s Australian Open prize money is about 16% of the organising body’s revenue.
In 2025, the US Open provided 16% of its previous year’s revenue to the players, with Wimbledon (13%) and the French Open – which does not make its figures available – offering a lower share.
The leading players have asked each Grand Slam for a staged increase over the next five years, eventually leading closer to the 22% mark which they receive at some of the ATP and WTA combined tour events.
This year’s rise in total prize money means the Australian Open is offering more than Wimbledon (£53.5m) and the French Open (£47.5m) did in 2025, although it is still behind the US Open (£67.4m).
The Australian Open starts in Melbourne on 18 January.
